This book presents a review of the work of the architect Michael Balz, pioneer of concrete-shell architecture. It discusses his projects, both realized and unbuilt, many being designed in collaboration with the renowned Swiss engineer Heinz Isler. Profusely illustrated with original drawings and photographs, Michael Balz: Shells and Visions caters to the increasing interest in the design and construction of free-form reinforced concrete shells consequent on the advent of 3D modelling and form-finding software. The book describes architectural designs and practical construction issues to motivate contemporary shell designers. Balz’s experience of dealing with such difficulties as incompatibility with non-structural features and the insertion of windows into shells, and the assessment of buildings’ long-term performance allow readers to learn more easily how to cope with such issues in their own work. The book introduces Michael Balz, his early work with other architects, including his work on pneumatic forms with Frei Otto, and his evolution into an exponent of organic architecture. It then discusses completed projects, including the outdoor Theater unter den Kuppeln (1976), Ballettsaal (1979) and Balz House (1981). Competitions Balz entered and unrealized shell projects also receive attention, as does his work on the urban scale, highlighting conceptual designs of mega-cities. His visionary megastructures encourage the exploration of innovative solutions for city spaces by architects faced with today’s increased urbanization. Michael Balz: Shells and Visions will be of interest to students and professionals in the fields of architecture, structural engineering, building and urban design. It’s reflections on the cultural and contextual aspects of Balz’s work will help the architectural historian to appreciate its long-term significance.

Laminated safety glass enables the safe construction of transparent structures. The mechanical behaviour depends on the polymeric interlayer both in the intact and in the post fracture state. In the present work, the mechanical behaviour of ethylene vinyl acetate-based (EVA) and ionoplastic interlayers is investigated for the intact laminated safety glass condition. In particular, the influence of the semi-crystalline structure on the stiffness behaviour is studied with X-Ray Diffraction, Differential Scanning Calorimetry and Dynamic-Mechanical-Thermal-Analysis. The studies on the mechanical behaviour of the interlayer in the fractured laminated safety glass were carried out with polyvinyl butyral-based (PVB) interlayers. First, the temperature and frequency (time) dependent linearity limits are determined in Dynamic-Mechanical-Thermal-Analyses, second, the nonlinear viscoelastic material behaviour is investigated with tensile relaxation tests at different temperatures and strain levels. Miriam Schuster, born in 1990 in Luxembourg, studied Civil Engineering from 2009 to 2014 at University of Luxembourg and TU Darmstadt. She focused and specialized on structural engineering. After working in the Luxembourgish engineering office Schroeder&Associés she returned to TU Darmstadt in February 2016 as a researcher in the Institute of Structural Mechanics and Design (ISM+D). In January 2022, she successfully defended her phd thesis with the topic “Characterization of laminated safety glass interlayers – Thermorheology, Crystallinity and Viscoelasticity”. Since then, she has been heading the glass and polymer unit of ISM+D as a postdoctoral researcher.

This book discusses the behaviour of isolated concrete bottle-shaped struts affected by internal expansion reactions (ISR). For that purpose, the numerical modelling of damaged concrete was performed using the Concrete Damaged Plasticity Model (CDPM) implemented in ABAQUS and validated the model through Sankovich's tests. A procedure to automatically obtain the concrete plasticity and damage parameters, essential for CDPM, was developed in Matlab. The inputs were the characteristic compressive strength of the concrete, the equivalent length of the finite element mesh and the ratio between the plastic and inelastic compressive strains. The results showed that the CDPM could represent the load-bearing mechanisms of isolated concrete bottle-shaped struts for a range of several stress levels to which these elements may be subjected in the panels investigated. The numerical simulations for different expansion levels consistently captured the expected damage profile of the panels and the load corresponding to the formation of the first crack, the estimated crack opening, and the ultimate load. For the panels investigated, the reduction observed in the failure load reached values close to 70%, the increase of the tensile plastic deformation was more than 60%, and the maximum crack opening can reach an increase of 113% when compared with those observed experimentally in panels without internal swelling reactions The book also offers a systematic review of the current state of knowledge and it is a valuable resource for scientists, students, practitioners, and lecturers in various scientific and engineering disciplines, namely, civil and materials engineering, as well as and other interested parties.
